Paper cup cover structure

ABSTRACT

A paper cup cover structure, comprising a cup body, being made of a paper, and comprising a cup opening disposed at a top thereof, a flat cup rim disposed around an exterior side of the cup opening, the cup rim having a flat face disposed at an exterior side thereof; and a cup cover, having a screw magzine circumferentially disposed at an inner face corresponding to the cup rim so that the cup rim and the screw magzine are rotationally combined with each other. In this manner, not only the cup body may more firmly stand with an assistance of the flat cup rim, the screw magzine may also rotationally reach a closure with the flat cup rim by stopping the screw magzine against the flat cup rim, so that the cup cover and the flat cup rim form a stable closure fixation.

FIELD OF THE INVENTION

The present invention relates to a cup cover structure, and particularlyto such structure where a screw magzine of the cup cover mayrotationally form a stable closure with a flat cup rim, whereby thepaper cup is provided with a flater, solid, safe and enduring structure,and achieves a less leakage and an efficacy of an easier fixation of thepaper cup.

DESCRIPTION OF THE RELATED ART

A conventional paper cup, as shown in FIG. 4, has a protruding rim 31disposed circumferentially at an upper end thereof, which is embededinto an indented groove 41 of a cup cover 4. Presently, all paper cupshave their protruding rim 31 presenting a circular side and rolled axisshape, and which has a weak structural strength. When the cup cover 4and the cup body 3 are embeded together, the protruding rim 31 of thecup body 3 is apt to have a deformity, i.e. become flattened and small.

At this time, between the indented gap 41 of the cup cover 4 and theprotruding rim 31 of the cup body 3 has a larger gap, resulting in thatthe porotruding rim 31 may not firmly be embeded into the indentedgroove 31. Hence, the cup cover 4 is apt to get loosened, or may nottightly or may only slightly cover the cup body 3, forming a non-closedstate. Out of the closed tate, the liquid within the cup may overflow,resulting in a conveient use of the cup and a unsanitary state.

SUMMARY OF THE INVENTION

It is, therefore, an object of the present invention to provide a cupcover structure, where not only a cup body may more stand firmly byusing a flat cup rim when the cup body is combined with a cup cover, acup screw magzine of the cup body may also rotationally reach a closurewith the flat cup rim, so that the cup cover and the flat cup rim form astable closure fixation, whereby the cup cover and the cup body arefixed tightly as a single body and the paper cup is increased in itsstructural strength and provided with a flater, solid, safe and enduringstructure, and thus achieves a less leakage and an efficacy of an easierfixation of the paper cup.

To achieve the above object, the paper cup cover structure according tothe present invention comprises a cup body, being made of a paper, andcomprising a cup opening disposed at a top thereof, a flat cup rimdisposed around an exterior side of the cup opening, the cup rim havinga flat face disposed at an exterior side thereof; and a cup cover,having a screw magzine circumferentially disposed at an inner facecorresponding to the cup rim so that the cup rim and the screw magzineare rotationally combined with each other.

In an embodiment, the cup rim is formed by plastic or paper by framemolding or paper molding.

In an embodiment, the cup rim has a downward presentation in a moldingand recovers to a horizontal presentation after being extracted.

BRIEF DESCRIPTIONS OF THE DRAWINGS

The present invention will be better understood from the followingdetailed descriptions of the preferred embodiments according to thepresent invention, taken in conjunction with the accompanying drawings,in which:

FIG. 1 is a schematic diagram of an outlook according to a firstembodiment the present invention;

FIG. 2 is a schematic diagram of an exploded state according to thefirst embodiment of the present invention;

FIG. 3 is an schematic diagram of a use state according to the firstembodiment the present invention; and

FIG. 4 is a schematic diagram of a cross sectional state of a prior artpaper cup.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, FIG. 2, and FIG. 3, a schematic diagram of anoutlook according to a first embodiment the present invention, aschematic diagram of an exploded state according to the first embodimentof the present invention, and an schematic diagram of a use stateaccording to the first embodiment the present invention are showntherein, respectively.

As shown, the cup cover structure of the present invention comprises acup body 1 and a cup cover 2.

The cup body 1 is made of a paper, and comprises a cup opening 11 and aflat cup rim 12. The cup opening 11 is disposed at a top of the cup body1. The flat cup rim 12 is formed around an exterior side of the cupopening 11 by using a frame molding or a parpar molding. The cup rim 12is formed by plastic or paper which may be biodegraded, and has a flatface 121 which is combined with the cup cover 2.

The cup cover 2 has a screw magzine 22 circumferentially disposed at aninner face thereof, at a place corresponding to the cup rim 12, so thatthe cup cover rim may rotationally combined with the cup rim 12 by usingthe the screw magzine 22. As such, the novel paper cup cover structureis formed.

In fabricating the cup cover structure of the present invention, the cuprim 12 is formed by plastic or paper by using a frame modling or a papermolding. The cup rim 12 has a downward presentation in a moldingfixture, but which recovers a horizontal representation after beingextracted from the molding fixture. In operation, the cup cover 2 may becombiend ontop the cup body 1 as a closure fixaiton. Not only the cuprim 12 having a flat shaped structure may reinforce the cup body 1, thescrew magzine 22 of the cup cover 22 may also stop against the flat cuprim 12 of the cup body 1 when the cup body 1 is combined with the bodycover 2, so that the screw magzine 22 may rotionally form a closurefixation with the flat cup rim 12. In this manner, the cup covre 2 andthe cup body 1 are tightly fixed as a single body, and the paper cup isincreased in its structural strength and provided with a flater, solid,safe and enduring structure, and thus achieves a less leakage and anefficacy of an easier fixation of the cup body 1.

In summery, the cup cover structure may effectively improve the demeritsof the prior art, where the cup body may stand firmly as possible as itcan by using the flat cup rim when the cup body is combeind with the cupcover by enabling the screw magzine to stop against the flat cup rim, sothat the screw magzine may rotationally form a closure fixation with theflat cup rim.

From all these views, the present invention may be deemed as being moreeffective, practical, useful for the consumer's demand, and thus maymeet with the requirements for a patent.

The above described is merely examples and preferred embodiments of thepresent invention, and not exemplified to intend to limit the presentinvention. Any modifications and changes without departing from thescope of the spirit of the present invention are deemed as within thescope of the present invention. The scope of the present invention is tobe interpreted with the scope as defined in the claims.
